FREDERICK BUI-LFORD PETRIE, 0F EOCHDALE, ENGLAND.

WOOL AND THE LIKE WASHING MACHINE.

Application filed November 23, 1915.

2' '0 all whom it may concern:

Be it known that I, FREDERICK BURFORD PETRIE, a subject of the King of Great Britain, residing at Rochdale, in the county of Lancaster, England, have invented certain new and useful Improvements in Wool and the like Washing Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in that type of machines for washing wool and other textile fibers and textile or other materials which comprises one or more liquor bowls in which the wool or the like to be washed is passed through the washing liqnor by means of rakes or other suitable devices and which are provided with automatic means for replacing the washing liquor removed from the said bowl or bowls at intervals.

My invention has for its object to quickly replace the discharged liquor and to thereby maintain the level or quantity of liquor in each bowl as nearly constant as possible. I attain this object by the mechanism illustrated in the accompanying two sheets of drawings, in which Figure 1 is a side view, Fig. 2 a plan, and Fig. 3 an end View. Fig. 4 is a plan of a modification.

Similar letters refer to similar parts throughout the several views.

Referring to the figures generally, which for example show a machine having two bowls a. and 6, according to one embodiment of my invention, to efl ect the said transfer of liquor, I provide each liquor bowl a and b with a reserve tank 0 located at the side thereof and with an overflow pipe cl leading to the latter, for controlling the maximum level of the liquor in the said bowls. I also employ a pump a and suitable connection f adapted to draw liquor from the reserve tank 0 into the respective bowl, a pipe 9 leading from the next following bowl 6 to the reserve tank 0 of the preceding bowl and a ball-tap or like device it attached to the pipe 9, so arranged that a reduction in the quantity of liquor in the reserve tank 0 opens the said ball-tap or the like device it and causes a flow of liquor from the following bowl 6, into the reserve tank e of the preceding bowl until the origi Specification of Letters Patent.

nal level is again attained. In the case where there is no following bowl. from which to obtain liquor, the said ball-tap or the like device of the last of the reserve tanks from which the liquor is to be drawn,

may be connected to a fresh liquor supply.

When a bowl has been filled with liquor to the level of its overflow pipe d, any ad ditional liquor drawn by the pump from the respective reserve tank 0 is carried back again to it by the respective overflow pipe (Z and a circulation of liquor is maintained which keeps the liquor in the bowl at a constant level. If some of the liquor in the first bowl a is run elf, the level of liquor therein will be momentarily lowered, but will be rapidly raised again until normal, by the pump 0 connected with the respective reserve tank 0. While the level of the liquor in the bowl is lowered below the overflow pipe d, no flow of liquor takes place down the overflow pipe at and consequently the level of liquor in the respective reserve tank 0 will be lowered and cause a flow to take place through the pipe 9 leading from the next following bowl or from the said fresh liquor supply, as the case may be, to the reserve tank 0 until the normal level in the reserve tank is again reached.

In lieu of the pipe g leading from one bowl to the tank of the preceding bowl, I may employ a pipe or trough 9 connecting the reserve tank '0 of one bowl to that of the next following bowl, see Fig. 4, in which case the lowering of the liquor level in the reserve tank of the one bowl will cause a flow of liquor into it from the reserve tank of the next following bowl, until the levels in the two reserve tanks are equal. The ball taps it serve in this example to prevent the liquor from flowing in the wrong direction.

I claim:

1. In a wool and the like washing machine of the type hereinbefore referred to, means for holding a reserve of liquor, means between the said means and the liquor bowls for continuously forcing the said reserve of liquor into the said liquor bowls, overflows in the liquor bowls for removing excess of liquor from the liquor bowls, connections between the said overflows and the first named means for returning excess liquor to the first named means, and automatic means in the first named means for admitting liquor to replace any liquor failing to return to the first named means after the removal of foreign matter and liquor from the liquor bowls, for the hereinbefore specified purpose.

2. In a wool and the like washing machine of the type hereinbefore referred to, means for holding a reserve of liquor below the liquor level of the liquor bowls, means for continuously forcing the reserve of liquor into the liquor bowls, means for conducting any excess of liquor in the liquor bowls back into the first named means, and means for automatically replacing liquor failing to return to the first named means by reason of the removal of foreign matter and liquor from the washing bowls, for the hereinbefore specified purpose.

3. In a wool and the like washing machine of the type hereinbefore referred to, a

reserve tank for each liquor bowl situated below the level of the liquor in the respective liquor bowl, an overflow outlet in each liquor bowl in communication with the respective reserve tank, a conduit connecting the liquor in each reserve tank with the respective liquor bowl, means in the said conduit for forcing the liquor from each reserve tank into its liquor bowl, a conduit between each reserve tank and the following washing bowl connecting the liquor in each washin bowl with the reserve tank of the preceding liquor bowl, and automatic means in each reserve tank for opening the last named conduit when the level of liquor in the reserve tank falls, for the hereinbefore speci- U fied purpose.

Signed at Manchester, England, this 12th day of November, 1915.
